IMPROVEM ENT IN CULTIVATO RS.

Specification forming part of Letters Patent No. 96,979, dated October226, 1869.

To aZZ w/wm t may concern.-

Be it known that I, J. A. SMITH, of Lacon, in the county of Marshall andState of Illinois, have invented certain new and useful Improvements inCultivators; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification, in which- Figure l represents aside elevation of my cultivator, and Fig. 2 is a perspective view of onebeam and the frame to which it is attached.

rlhe nature of my invention consists in the peculiar construction of theplow-beams, and of the device to which they are attached.

It further consists in attaching vertical bars to the double-tree, so asto bring the draft in a line with the beams of the plow, in the mannerset forth.

A in the annexed drawings represents the wheels; B, the plow-beams, andC the axle.- tree.

D D designate two quadrangular frames, of cast-iron or other suitablematerial. y The upper end of said frames are securely fastened to theunder surface of axle-tree C in such a position as that the outer sideof the frames will be flush with the ends of the axle-tree. The bottomof frames D have a slot in them extending their whole length, and alsoseveral perforations opening in said slots, the object of which will behereinafter explained. On the outside of frames D are fastened, withscrew-bolts, the plates g, which can be adjusted to suit the size of thewheel, as the axle or spindle on which the wheel revolves is attached tosaid plate g.

h represents a cylindrical bar, the upper end of which enters a hole inthe under side of axle-tree' C, and the lower end rests in one of theperforations in the bottom of frame D.

F represents a metal plate, the inner edge of which is secured to bar h.To plate F is pivoted one end of plate G, the opposite end of G beingsecurely fastened to beam B. The bar h, to which the plow-beam is thusattached, can be removed to any one of the holes in the bottom of frameD, corresponding holes being made in the upper end of said frame toreceive said bar. By this arrangement the plow-beams can be moved nearerto or farther l from the corn-rows, at the pleasure of the operator:

H represents the double-tree, which is pivoted to the bottom of tongueT. To each end of double-tree H is fastened the perforated metal pendantm.

a designates the single-trees, which can be so as always to bring thedraft in a line with the plow-beams, and thus prevent the horses collarfrom pressing unduly on the top of his neck and shoulders.

L. On the projecting ends of said tie an opening is made, sufficientlywide to receive the beams B, which can be elevated at their outer endand placed in said opening when the cultivator is to be removed from onepart of the iield to another.

S represents a brace, which binds the frames D to the hounds L.

I I represent two metal rods, one end of which is hooked into pendants mand the other ends attached to a cord, which passes over a pulley, t,connected with axle-tree C. The rods I I serve to brace the pendants mand also to govern the motion of the doubletree H.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

l. The frames D D, when provided With plates g g, and adjusting-holes attop and bottom, substantially as and for the purpose described.

2. The combination of the beams B B with the vertical cylindrical bars hh, when said bars are provided With the plates G and F, the plates beingpivoted together, substantially as and for the purpose specied.

3. The double-tree H, provided with pendants m m, in combination withrods I I or their equivalent, the said rods being connected with apulley, t, on double-tree H, in the manner and for the purpose setforth.

In testimony that I claim the foregoing as my own I afx my signature inpresence of two witnesses.
